Feasibility and Effects of Water Quality on Bait-Fish Culture in Aerated Sewage Treatment Lagoons in Vermont

摘要

Golden shiners (Notemegonus chrysoleucas) were successfully cultured in 1 cu m floating cages in the final lagoon of an aerated lagoon-type sewage treatment facility in Milton, Vermont. The mortality rate at densities of 50 and 100/cu m was 6% and 8% respectively, and at 200/cu m was 34% over a two-month period. Zinc concentration increased from 2.0 to 6.6 ppm during the same period, while cadmium, lead, and chromium concentrations did not change significantly.
